Render into a static cubemap from this camera.
faceMask
is a bitfield indicating which cubemap faces should be rendered into. Each
bit that is set corresponds to a face. Bit numbers are integer values of CubemapFace enum.
By default all six cubemap faces will be rendered (default value 63 has six lowest bits on).This function will return false
if rendering to cubemap fails. Some graphics hardware does not
support the functionality.Note: This is a Unity PRO feature.See Also: Cubemap assets, Reflective shaders.// Render scene from a given point into a static cube map. // Place this script in Editor folder of your project. // Then use the cubemap with one of Reflective shaders! class RenderCubemapWizard extends ScriptableWizard { var renderFromPosition : Transform; var cubemap : Cubemap; function OnWizardUpdate () { helpString = "Select transform to render from and cubemap to render into"; isValid = (renderFromPosition != null) && (cubemap != null); } function OnWizardCreate () { // create temporary camera for rendering var go = new GameObject( "CubemapCamera", Camera ); // place it on the object go.transform.position = renderFromPosition.position; go.transform.rotation = Quaternion.identity; // render into cubemap go.camera.RenderToCubemap( cubemap ); // destroy temporary camera DestroyImmediate( go ); } @MenuItem("GameObject/Render into Cubemap") static function RenderCubemap () { ScriptableWizard.DisplayWizard.<RenderCubemapWizard>( "Render cubemap", "Render!"); } }
